Some exceptions may apply based on panel type.

How to test a solar panel charge controller.

Make sure that the alligator clips are in the right port to find the. That being done connect the solar panel to the controller and also the controller to the solar batteries. Solar charge controller what is it and how it works in a solar power system duration. Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black.

Ensure that the multimeter is set to measure volts. Set the measurements of the multimeter to dc amps. How to test a solar panel voltage and current duration. To test solar panel amperage output put your solar panel in direct sunlight set your multi meter to the dc amps setting.

Check both manuals the battery manual and the controller manual and make sure that the controller is set for the proper battery agm wet cell etc and temperature lead acid batteries are very sensitive to change voltage and battery temperature. You will next connect the solar panel to the controller as well as the controller to the battery. The next step in the process is to disconnect the positive cable that runs from the battery to the controller. To ensure that you don t blow your device s fuse set the maximum amperage sensitivity to well above your expected reading.

Open circuit voltage can vary depending on your solar panel but the readings we are usually looking for are in the range of 15 to 23v. Disconnect the positive cable that is. Measure the voltage between the ve and ve terminals by connecting the negative contact from the voltmeter to the negative on the panel and the positive contact on the voltmeter to the positive on the panel. Set the multimeter to 10 amps.

Angle the solar panel towards the sun.
